RF 83

[holtrp]

I have heard the RF-83's run off a Harman/Kardon receiver, a 100w Harman/Kardon amp, a 2306 Denon receiver, a 3808 Denon receiver, an Emotiva XPA-3, XPA-5 and my current setup, an XPA-2.

The harman stuff was at the AV shop and everything else has been in my living room.

I haven't done a whole lot of listening without my subs. I played them full range when I first picked them up with and without an amp and it was certainly noticeable. You won't regret getting an amp. These are pretty serious speakers and really come alive when you can throw some watts at them. My RF-83s replaced an older set of reference Paradigms and blew them out of the water both with and without the amp.

Still, if you are really looking for heavy bass, you'll need a subwoofer.

I am learning more and more through the days, but i believe i have most of it pat down.

A lot of people and i mean a lot seem to believe that watts are watts
and if a speaker can be powered to a acceptable volume level without
distortion its enough and would not require a amp upgrade.

But to me of course this does not make sense to me after taking a closer
look into the physics of how power works and came to a conclusion that
those people were biased pricks who can only afford cheap equipment (no offense xD).

So with the RF83/7 yes they are very efficient speakers but this is
mostly only because of the horn loaded tweeters, these things use only
about 15 watts if that of any kind of power.

As we all should know though most of the required power to drive a
speaker is down below 200hz range and this is where a lot of the good
bass sounds come from, bass guitar, drums, kick drum.

The RF83/7 are known to have a impedance drop of 2.8ohm at around the
200hz and under mark, but this isn't just because of the frequency its
because it has to drive three 8" or two 10" at the same time and as you
can imagine can be quite difficult because of how much air it has to
push and how fast.

You can supply these speakers with low watts and get really loud levels
but you will not get the full sound quality that the speakers can
produce unless you supply high current and clean power so it can handle
the impedance drops and be able to get a more powerful control over the
woofers to produce better low frequency's



Said it like i had experienced it, but i am convinced by my research
that my theory is correct and i will see in time when i get a beast PSU
and prove myself right , but i have read countless people upgrading their amps and the speaker quality would improve across the bass frequency always.

I know i promised pictures but my room is real crappy and would get such a hard time because of it lol.

Well...It is about frequency because to hit those notes you need to engage those drivers that you are referring too...other than that you seem to be on the right path.

Thanks

I wasn't excluding the frequency, i was just saying it isnt just the frequency i mean if you compare it running one woofer compared to all three, those three running at the same time would require more power than it just running just the one.
